The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.

Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.

Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.

I take this during the flu season regularly. So far so good for that. I recently started purchasing it for my dad when he got a horrible case of the shingles across his ribs and around to his back. Never seen any thing like it before. To date he is doing a lot better. He says he is starting to feel good again. Along with the elderberry I've also purchased L-Lysine and sublingual B-12 for his nerve ending pain. He is taking a combination of the three in high doses and it is helping.

I'm a RN practicing in SC, and recently developed shingles. I spoke to a co-worker of mine, also an RN, who had developed post-herpetic neuralgia after a shingles outbreak, and she experienced profound pain lasting several months. This complication occurred even though she had taken antivirals prescribed by her medical doctor, and started them immediately after the rash appeared.
I also spoke to a nurse who gave me the recommended medical protocol for shingles, which again used antivirals, which had to be started within 24 hours from the time the rash appeared. The antivirals were very expensive, and had a number of undesirable side effects.
I then went to the internet and did some research. I also spoke to a friend of mine who practices naturopathic medicine. That is where I heard about this product. I was told to take one tsp of the concentrate undiluted every hour for 24 to 48 hours, then to reduce it to 2 Tbsp diluted in 8oz of pure water every six hours. I was also told to take 1,000 mg of L-Lysine every 6 hours until the rash dried up. It was important to start the treatment within 24 hours of breaking out in a rash. I ordered this product, then went to our local Natural Food Store and purchased enough of another similar product to last me until this arrived. Each bottle from my local food store had only 4 oz, and were overpriced at 20.00 per bottle. I used them until Dr. Dunners Sambu arrived two days later.
Naturally, I had a lot of pain, and many blisters. I also ordered a wonderful product not carried here from another site for local pain relief. It too was amazing, and made the pain much more bearable.
Within one week, my rash was completely healed, and my pain completely gone. I was told by my naturopathic MD friend to continue the Dr. Dunner's Sambu product, 2 TBSP in 8 oz of water every six hours for one more week to avoid developing the post herpetic neuralgia. My NP friend also said to reduce the L-Lysine to 500 mg per day and to take it for one more week then stop. I have NEVER seen anyone get over shingles this quickly, even though I have been a nurse working in a hospital for 30 years.

I like this product but they say it is only good after being open for 3 weeks. What a waste! It is an enormous amount for something to be used in that small time frame. If I get it again I will try to find a much smaller bottle.

I found I got instant results with my ongoing sinus problem while taking this product. I am trying to source something similar within Australia to try to lessen my carbon footprint but if I can't I will continue to use this one.
